Laser system with multi-stripe diode chip and integrated beam combiner

摘要

A multi-stripe laser diode chip (120) is integrated with a beam combiner (102) on a single optical bench (100), and is thus, applicable to placement in a single pigtailed module. Specifically, multiple beams (150A, 150B) emitted from the chip stripes (110A, 110B) are spatially merged using a birefringent material (500) and then coupled into an optical fiber (700). The use of the birefringent material provides an efficient solution for generating the merged beam (520), which can be coupled into a single optical fiber. <IMAGE>
